Logging Terms - R -
RATED CAPACITY: The maximum load a system, vehicle,
machine or piece of equipment was designed by the manufacturer to handle.
REACH: A steel tube or wood timber or pole connected
to the truck and inserted through a tunnel on the trailer. It steers the trailer
when loaded and pulls the trailer when empty.
RECEDING LINE: The line on a skidder or slackline
comparable to the haulback line on a yarder.
RELOAD: An area where logs are dumped and reloaded or
transferred as a unit to another mode of transportation.
RIGGING CREW: Crew and equipment that drags logs to an
area called a deck or landing. From the deck, logs are loaded onto trucks for
transport.
RIGGING CUT: The bucking of non-merchantable trees
which have been felled or blown down to facilitate easier access to the area by
the rigging crew.
RIGGING CUT OR WEAKENING CUT: A tree may be lying in
such a position that a normal bucking cut cannot be made safely. In order to
facilitate yarding or skidding, the faller will make partial bucking cuts from a
safe position, perhaps two log-lengths apart.
ROLLWAY: Any place where logs are dumped and they roll
or slide to their resting place.
ROOT PULL: The pulling out of a portion of a tree's
root system. Generally a result of not cutting up the corners of the holding
wood close enough on a large or heavily leaning tree.
ROOTWAD: The ball of a tree root and dirt that is
pulled from the ground when a tree is uprooted.
R.O.P.S.: Roll over protection structure.
RUNAWAY: A tree that has rolled or slid downhill below
previously felled and bucked timber.
RUNNING LINE: Any line that moves.
RUSSIAN COUPLING: An incomplete bucking cut as a
result of an unsafe bucking situation. In such an instance the faller only
partially cuts through the tree. This situation can be very dangerous to the
rigging crew. If a Russian coupling is left, the tree should be marked and
supervisors notified.
